I recently wondered how it is possible to shutdown Windows in some prior set time lets say in 30 minutes, 1 hour, 3 hours or 8 hours.

That's handy especially on servers that are being still in preparation install time and you have left some large files copy job (if you're migration files) from Old server environment to a new one
or if you just need to let your home WIndows PC shutdown to save electricity after some time (a very useful example is if you're downloading some 200GB of data which are being estimated to complete in 3 hours but you need to get out and be back home in 2 or 4 days and you don't want to bother connecting remotely to your PC with VNC or teamviewer then just scheduling the PC / server to shutdown in 3 hours with a simple is perfect solution to the task, here is how:

1. Open Command Prompt (E.g. Start menu -> Run and type CMD.EXE)

2. Type in command prompt

shutdown -s -t 10800

If you by mistake has typed it to shutdown earlier and suddenly you find out your PC needs to be running for a short more time in order to cancel the scheduled Shutdown type:

shutdown -a

Shutdown Windows command -s flag has also a possibiltiy to not shutdown but just logoff or if you just need to have the system rebooted a reboot option:

If you are working in a large corporation such as (HP or HPE – Hewlett Packard Enterprise (HPE is the new splitted company brand name for the Software and Servers division of ex-HP) / IBM / Dell or any other company with the size of top fortune companies and you Computer Domain admistrator has forced your work PC to already use Skype for Business instead of the good tested Lync Client along with the goodies and PROS of having the newer Skype for Business (S4B) as usual for old fashened users like me and the avarage employee the New S4B interface will turn into nightmare with all this circled names and more buttons and the annoying Skype Blue Theme.

For anyone who has even basic idea of design and aesthetics, I believe the default Theme of Skype For Business will be evaluated as a serious "interface downgrade" compared to the simple looking Interface and White Skin of Lync Client.

With this said it will be logical for the end user like me to desire to customize a bit default S4B Skin to make it more elegant looking like Lync 2013 client but guess what there is a Surprise if you google around, Skype For Business just like the regular Skype client doesn't have integrated support for Skins / Themes.
To make the horror complete, many big corporations are choosing to migrate their Email infrastructure from the classical and well tested Windows Domain with Exchange Server to Microsoft Office 365 (Cloud services),
which makes the dependency on M$ products even bigger and in the long run control and spying on people's email and information (people's data security even worsers) as you know how hackable Windows prooved to be over the years.

Well for those who remember the good old times of IRC (Internet Relay Chat) andICQ (I seek you)🙂 and even Jabberwhen chatting emerged and boomed into popularity all the chat clients nomatter whether it was afree software under GPL / BSD license or it was a Proprietary licensed software, there was always alternative on the Interface Outlook of the Chat clients and on practically all popular Chat / Audio / Video communication Standards / Protocols, there used to be some option for the users to use either a different client or to customize the outook of the program.

Well now the big surprise with Skype Protocol which was purchased by Microsoft some years ago back is this terrible already M$ program doesn't have any option for changing the Theme and even basic customization besides the ones provided by default by Microsoft. For my surprise such a trivial and everybody used program like Skype with perhaps already 1.5 or 2 Billion or even more users doesn't have even basic support for customization !!!
To make the Skype program use horror story even worser Microsoft does upgrade the Skype client agressively and for the last 3 or 4 years Skype is owned by Microsoft the interface gets changing slightly or even completely with every next release.

Now with latest Skype versions since a 1.5 year or so the agressiveness of the program even increased further as it wants you to automatically upgrade, every time you run Skype.
With this in mind and the fact, I have to spend about 8 to 10 years on the PC with Skype for Business switched on on my notebook with no option to use Lync for communication because of the Domain Exchange forcing the changes to all of the users within our EMEA.

So after some serious digging on the Internet, the only work around to change the Skype For Business Theme available by a couple of sources is to Revert Back the Skype User Interface to Lync 2013 Client by changing a value to the Windows registry and get back the good old elegant Lync interface instead of S4B.

Because the Domain administrator has forced a policy to automatically offer Change of Lync Interface to Skype for Business on every notebook boot to disable EnableSkypeUI registry value and make Skype appear in the good old Lync UI, I've created also a tiny Batch script lync_ui.bat with following content:

Note that both skype.reg and lync_ui.bat should be existing in my case in C:\Users\georgi\scipts , change this path to whatever your username is and create scripts folder in your User Home dir.
If unsure about the home directory name you can check it from command prompt with:

C:\Users\georgi> echo %HOMEPATH%
\Users\georgi

To make the lync_ui.bat (script invoking skype.reg) be executed on every PC boot, you need to add it to:

If you administer a university shared free shell Linux server, have a small community of *NIX users offering free accounts for them, or responsible for Linux software company with development servers, where programmers login and use daily to program software / websites its necessery to have tightened security rules with a major goal to keep the different user accounts processes separate one from other (hide all system and user processes from single logged in user).

Preventing users to see other users processes is essential for Linux servers which are at high risk to be hacked. At earlier times to achieve hiding all processes besides own ones from a logged in user was possible by using A kernel security module Grsecurity.In latest currenlt Linux kernel version 3.2+ (on both Debian (unstable) / Ubuntu 14.04 / RHEL/CentOS v6.5+ above) you can hide process from other user so only root (useruser) can see all running process with (ps auxwwf) with a native kernel option hidepid.

Configuring Hidepid

To enable hidepid option you have toremount the /proc filesystem with the Linux kernel hardening hidepid option, to make it one time setting on already running server issue:

mount -o remount,rw,hidepid=2 /proc

To make the hidepid setting permanently active its necessery to modify /proc filesystem settings in /etc/fstab

hidepid=1 – Means users may not access any /proc/ / directories, but only ones owned by them.Important files like cmdline, sched*, status are now protected to read from other other users.

hidepid=2 – Means hidepid=1 plus all /proc/PID/ will be invisible to other users besides logged in. Using this options stops Cracker's from gathering info about running processes, indication of daemon (services) which runs with elevated privileges, other user running processes (some might contain password) passed as argument or some sensitive data. Revealing such data is frequently used to get versions of local / remote running services that can be exploited.

Below is output of htop of a logged in user on hidepid activated server:

Probably many people which are my age (I'm aged 30 now), spent many days and sleepless nights being totally addicted playing probablyone of the most addictive (and in my view greatest strategy game of all time) – Heroes of Might and Magic II (HOMM2).
In that thoughts it will be a great news for you if you're owning smartphone that you can turn-back some nice memories and play (for free) a port of Heroes 2 for Android.

Free Heroes 2 Android port is it is made to support multiple screened devices so game version could be played on both Android Tablet a tiny screen smart phone or a middle sized mobile. Also Free Heroes 2 mobile port allows you to choose 'The Magnifying glass' option on first game boot, so if you're on a tiny screened mobile you can still zoom by pointing on a game object. Free Heroes 2 Android port is there thanks toGerhard Stein who is also an author of OpenTyrian mobile phone port and the amazing old computer jump-and-run arcadeCommander Keen. Game pointer controls of FHeroes2 are pretty convenient and playing the game is almost as confortable as played with a PC mouse.Free Heroes 2 is port of Free Heroes 2 engine – Free implementation of Heroes of the Might and Magic II engine in SDL and because SDL is platform independent Free Heroes is also available for both Windows / Linux. Maybe here is time too mention that Heroes2 original DOS game works perfectly on any modern Linux distribution when started through DOSBOX DOS emulator.

By default Free Heroes2 has no game campaign support yet. In order to enable campaing support into Free Heroes 2, download FULL Heroes 2 game – put data files to mobile SD card to dir app-data/net.sourceforge.fheroes2 and campaign option will be there too.

Heroes of Might and Magic 2 – The succession Wars (or HEROES2, as it is widely known in Gamers communities) is a turn based strategy game from year 1996 developed by Jon Van Caneghem by his New World Computing company it was marketed under on the market under brand of 3DO Company. Heroes II was voted the sixth-best PC game of all time by PC Gamer in May 1997. Heroes2 has also a game expansion pack called the Price of Loyalty released in 1997 as well as Heroes of Might and Magic II – Gold – from 1998. The game graphic design looks very beautiful and combined with the soundtrack makes playing it an awesome and calming experience. The game is very notable especially for soundtrack which is all of a beautiful classical music.

Gameplay

The titular heroes (horse) are player characters who can recruit armies, move around the map, capture resources, and engage in combat. The heroes also incorporate some role-playing game elements; they possess a set of statistics that confer bonuses to an army, artifacts that enhance their powers, and knowledge of magical spells that can be used to attack enemies or produce strategic benefits. Also, heroes gain experience levels from battle, such that veteran heroes are significantly more powerful than inexperienced ones.

On a typical map, players begin a game with one town of a chosen alignment. Each town alignment hosts a unique selection of creatures from which the player can build an army. Town alignment also determines other unique traits such as native hero classes, special bonuses or abilities, and leanings toward certain skills or kinds of magic.

Towns play a central role in the games since they are the primary source of income and new recruits. A typical objective in each game is to capture all enemy towns. Maps may also start with neutral towns, which do not send out heroes but may still be captured by any player. It is therefore possible, and common, to have more towns than players on a map. When captured, a town retains its alignment type, allowing the new owner to create a mixed army. A player or team is eliminated when no towns or heroes are left under their control. Usually the last player or team remaining is the victor.

As heroes visit special locations called obelisks, pieces are removed from a jigsaw puzzle-like map, gradually revealing 'The Ultimate Artifact location to the player. Once found, it confers immense bonuses to the player capable of breaking a stalemate: the grail can be taken back to a town and used to build a special structure, while the ultimate artifact provides the bonuses directly through possession.

Whenever a player engages in battle

The game changes from the adventure map display to a combat screen, which is based on either a hexagonal or square grid. In this mode, the game mimics the turn-based tactics genre, as the engaged armies must carry through the battle without the opportunity to reinforce or gracefully retreat. With few exceptions, combat must end with the losing army deserting, being destroyed, or paying a heavy price in gold to surrender. Surrendering allows the player to keep the remaining units intact. Battles can be led army army to army or castles / villages can be fight and (captured) occupied. Owning a town gives your hero daily an income of money later used to buy and upgrade castle buildings.

Also you your moved heroes could overtake mines producing different goods like minerals, sulfur, gold, emeralds etc. Building different buildings and building war units for army usually cost gold and some kind of resource.

Game Story

Heroes II history continues afterHeroes I. Ending of Heroes I results in Lord Morglin Ironfist's victory. In the following years, he has successfully unified the continent of Enroth and secured his rule as king. Upon the king's death, his two sons, Archibald and Roland, vie for the crown. Archibald orchestrates a series of events that lead to Roland's exile. Archibald is then declared the new king, while Roland organizes a resistance. Each alignment is represented by one of the game's two campaigns. Archibald's campaign features the three "evil" town alignments, while Roland's campaign features the three "good" town alignments.

If Archibald is victorious, Roland's rebellion is crushed, and Roland himself is imprisoned in Castle Ironfist, leaving Archibald the uncontested ruler of Enroth. The ending, however, results in Roland's victory, with Archibald being turned to stone by Roland's court wizard, Tanir.

Budget of European Union for 2011 is 142 billion Euro. Main source of budget income are installments from country members. Installments paid to EU consist about 1 of countries GDP – and approximately this is the amount of money paid per EU country member.

For Bulgaria installment is about 426 million euro. The bigger GDP is the bigger the amount of money the respective country pains to the overall European Union budget. Even though payments of member countries is only 1% of GDP, this is the source for about 70% of income of EU.

Other source of money for European Union community comes from VAT taxes, and countries customs taxes (over import / export goods) collected on external border of EU community. In national budgets. Member countries give out 75% of their quotes over the custom incomes, collected in external borders of EU. In national counry budget only 25% of money made from customs control imports and imports influx. In Bulgaria's case we can be talk about the import crossing borders of Macedonia, Serbia and Turkey. Import from VAT taxes in 2011 are 3 370 billion leva and from customs 131 million leva. What percantage of this money went to European Union knows only experts.For last year the Brussels money for Bulgaria are only 1.33 billion Euro (just to compare Poland received 16 736 billion euro). What is even more sad is that money coming from European union for so called funds influx into the pockets of well known oligarchs.

As it looks even though the glorifications with which Bulgarian government gave to the acquisition of this 1.33 billions eur-obrussel gifts during last year our coutnry still remains net sponsor of European budget. Here are not included the country econonic losses of the membership in EU, for example the closure of reactors of our Nuclear Power Plant in Kozloduy. In mean time about 1% of budget of EU community comes from installments from EU employees, unspent money from EU country members as well as receipts from fines from firms and companies for breachment of laws for protectition of competition and normative acts.
Primary supplier in European Union budget is Germany.

In 2011, Germany paid to EU 27 954 billion euro. This is about 19.7 of all the Union incomes.

Second to Germany by paid country member fee to EU is France with 23.273 billion euros, about 16.4% of all EU income.

Third is Italy with 18 447 billion euros or 13% of all EU budget.

As prior mentioned in 2011 direct installment of Bulgaria is 0.426 billion euro (without VAT quotes and incomes from taxation). Less installments paid Esthonia, Lithuania, Malta, Cyprus, Luxemburg (!!!) and Slovenia. Even though all this countries has less teritoriy and less population all this countries are much richer and has ahigher GDP per capita!

Luxemburg – 1.52 euro a day per person, followed by Danes, Belgians, Swedes, Dutch, Irish, French and Austrians (ranging from 1.47 euro to 0.98 euro).

As some of European Union citizens might not known,few million of Euro of this money is spend on a move of European deputies from Brussels to Strasburg every month (money given for travel costs of EU deputies and physical move of resources from Brussels to Strasburg). The exact sum spend per year for this unmeaningful move (in order to fulfil European community old legislation varies from 150 to 200 million a year!)

If you're configuring a new Webserver or adding a new VirtualHost to an existing Apache configuration you will need to restart Apache with or without graceful option once Apache is restarted to assure Apache is continuously running on server (depending on Linux distribution) issue:

Meaning of 0.0.0.0 is that Apache is configured to Listen on Any Virtualhost IPs and interfaces. This output is usually returned whether in Apache config httpd.conf / apache2.conf webserver is configured with directive.

Listen *:80

If in netstat output there is some IP poping up for example "192.168.1.1:http", this means that only connections to the "192.168.1.1" IP address will be accepted by Apache.

Another way to look for Apache in netstat (in case Apache is configured to listen on some non-standard port number) is with:

netstat -l |grep -E 'http|www'

tcp 0 0 *:www *:* LISTEN

As sometimes it might be possible that Apache is listening but its processes are in in defunct (Zommbie) state it is always a good idea, also to check if pages server by Apache are opening in browser (check it with elinks, lynx or curl)

To get more thorough information on Apache listened ports, protocol, user with which Apache is running nomatter of Linux distribution use lsof command:

Nowadays having a a touch screen mobile phone has become like a standard. I'm not such a big fan of Touch screen technology, thus I've been fighting with the idea to own a touch screen phone for a year or so. Just till recently I happily lived with my old Nokia 9300i with a physical QWERTY keyboard for already 4 years.

Unfortunately lately while talking with my Nokia I started getting frequent voice interruptions missing words in my phone call conversations and need to ask person I'm talking to, to repeat his words / sentence in order to understand what is communicated .. I'm economic person and therefore don't like bying anything new if it is not absolutely necessary so I opened the phone and clean it hoping that this will solve the conversation issues but with no luck. With this half-usable mobile my only option left was to buy a new mobile phone.

I'm not very rigorious on what a mobile phone should be and I'm very much minimalist by heart so I was thinking of bying new cheapest available Nokia phone on the market and solve my "issue" quick and efficient, only problem was I'm quite used already of using my handy QWERTY phone as a note taking device thus I preferred to not buy a keypad mobile phone but get again a smartphone with physical QWERTY.

I have consulted with some friends who are more knowledgable on what's latest on mobile phone market with a question what will be a good substitute for my Nokia Communicator 9300i and heard comments like:'IPhone is the most functional and superior in interface', while some friends and colleagues adviced me:'Choose an Android based phone as Android is Linux based and gives more freedom to the user as well as has more free applications to install'

I appreaciated my friends help but I didn't like the idea to buy a Smartphone with a touchscreen display – virtual keyboard is not so confortable as having a physical one and besides this is a very slow interface compared to physical keys. Thus initially strongly rejected the idea of bying a phone without a physical keyboard. After some weeks of pondering and checking in the market – in 3 Major mobile operators shops in Bulgaria MTel, Globul and VIVACOM and HANDY store. I've find out currently on the market there is no good price / quality and functionality ratio (qwerty keyboard mobile) available. My options were limited to either by a Nokia Asha 210 or some variance or a Blackberry mobile.

In first glimpse I liked the Nokia ASHA 210 – QWERTY powered mobile but after noticing the blue Facebook "F" button got quickly jolted.
The sales lady offered me a couple of other Nokias with Qwerty keyboard as well as a Blackberry 9320 Curve.

After a quick test of all QWERTY mobiles, found the intertface on both is so inferior to IPhone's IOS and Android based phones.
I asked my HP workmates for advice of a good QWERTY bundled mobile phone with Android and was referred to Motorolla Droid 3 – which seems to among the only options on the market for mobile Phone which have both Android Operating System and a Physical QWERTY keyboard. Motorolla Droid 3 seemed to be exactly the mobile I was looking for but unfortunately it is not available in Mobile phones stores in Bulgaria and only in bulgaria is only offered for sale as a second hand and I had to buy it over the Internet (I prefer not to buy on the Internet). Even if I bought it as second hand DROID 3's price is too high for my budget – 250 EUR!

I wanted to buy economic phone and same time to have a good balance between price and phone modernity, same time don't tie myself with mobile operator yearly tax plan thus decided to pay my whole mobile price in cache (no credits, no binding 2 / 3 year conversation plans).

After evaluating the options on Market I stopped on two mobiles identical by price 150 EUR I could choose between Samsung Galaxy Trend Lite or ZTE Blade 3. The sales lady adviced me its better to get the ZTE Blade 3 than Samsung Galaxy Trend Lite (S7350) because ZTE has better Camera (5 Mpixels), a better Display and has much less hardware issues than Samsung Galaxy Lite.

Finally I bought the ZTE Blade 3 and nowdays I'm trying to get used to it and to be honest even with a week passed I still can't get used to the Virtual Keyboard…

Android interface is quite shiny but a little bit chaotic if compared to design use interface I've tested on IPhones. Android OS seems to behave very weird at times but in general is quite easy to use. Managing / installing / Removing applications from Google AppStore is done by only 2 clicks. My major concern on Android is its highly addictive. I've catch myself, since last week I spend much more time using my mobile than before with my Nokia Communicator …

To conclude it I would say living with a smartphone has its advantagous (you can easily check weather prognosis / news) and do a number of things with it, but it is addictive .. obviously its easy to become an Android addict and spend your free time on useless stuff like installing / testing new apps and playing with phone. Having a smartphone just like I priorly suspected is a big time eater and it seems my hypothesis that its better to live without a smart phone is true. But who knows, perhaps its just a moment addictiveness just like with any new thing posession – time will show. In meantime I believe my ZTE Blade III – purchase was a good deal as it gives me opportunity to explore Android OS. I'll stop here with my ranting and excuse myself if the article was too boring …Please drop me a comment with mobile types and names who had QWERTY keyboard and a modern OS. Very sadly it seems the QWERTY hardware keyboard mobiles will soon be dead and gone …

I’ve used K3B just recently to RIP an Audio CD with music to MP3. K3b has done a great job ripping the tracks, the only problem was By default k3b RIPs songs in OGG Vorbis (.ogg) and not mp3. I personally prefer OGG Vorbis as it is a free freedom respecting audio format, however the problem was the .ogg-s cannot be read on many of the audio players and it could be a problem reading the RIPped oggs on Windows. I’ve done the RIP not for myself but for a Belarusian gfriend of mine and she is completely computer illiterate and if I pass her the songs in .OGG, there is no chance she succed in listening the oggs. I’ve seen later k3b has an option to choose to convert directly to MP3 Using linux mp3 lame library this however is time consuming and I have to wait another 10 minutes or so for the songs to be ripped to shorten the time I decided to directly convert the existing .ogg files to .mp3 on my (Debian Linux). There are probably many ways to convert .ogg to mp3 on linux and likely many GUI frontends (like SoundConverter) to use in graphic env.

I however am a console freak so I preferred doing it from terminal. I’ve done quick research on the net and figured out the good old ffmpeg is capable of converting .oggs to .mp3s. To convert all mp3s just ripped in the separate directory I had to run ffmpeg in a tiny bash loop.

Why would anyone disable ACPI support on a server machine??
Well ACPI support kernel loaded code is just another piece of code constantly being present in the memory, that makes the probability for a fatal memory mess up leading to a fatal bug resulting in system crash (kernel panic) more likely.

Many computers ship with buggy or out of specifications ACPI firmware which can cause a severe oddities on a brand new bought piece of comp equipment.

One such oddity related to ACPI motherboard support problems is if you notice your machine randomly powering off or failing to boot with a brand new Linux installed on it.

Another reason to switch off ACPI code will would to be prevent the CPU FAN rotation from being kernel controlled.

If the kernel controls the CPU fan on high CPU heat up it will instruct the fan to rotate quickly and on low system loads it will bring back the fan to loose speed.
This frequent switch of FAN from high speed to low speed increases the probability for a short fan damage due to frequent changes of fan speed. Such a fan damage leads often to system outage due to fan failure to rotate properly.

Therefore in my view it is better ACPI support is switched off completely on servers. On some servers ACPI is useful as it can be used to track CPU temperature with embedded motherboard sensors with lm_sensors or any piece of hardwre vendor specific software provided. On many machines, however lm_sensors will not properly recognize the integrated CPU temperature sensors and hence ACPI is mostly useless.

There are 3 ways to disable fully or partially ACPI support.
- One is to disable it straight for BIOS (best way IMHO)
- Disable via GRUB or LILO passing a kernel parameter
- Partial ACPI off-ing - /disabling the software that controls the CPU fan/

1. Disable ACPI in BIOS level

Press DEL, F1, F2, F10 or whatever the enter bios key combination is go through all the different menus (depending on the vios BENDOR) and make sure every occurance of ACPI is set to off / disable whatever it is called.

Below is a screenshot of menus with ACPI stuff on a motherboard equipped with Phoenix AwardBIOS:

This is the in my opinon best and safest way to disable ACPI power saving, Unfortunately some newer PCs lack the functionality to disable ACPI; (probably due to the crazy "green" policy the whole world is nowdays mad of).

If that's the case with you, thanksfully there is a "software way" to disable ACPI via passing kernel options via GRUB and LILO boot loaders.

The kernel option root=/dev/VolGroup00/LogVol00 means the the server is configured to use LVM (Logical Volume Manager).

b) Disabling ACPI on GRUB version 1.99 +

This version is by default installed on newer Ubuntu and Debian Linux-es.

In grub 1.99 on latest Debian Squeeze, the file to edit is located in /boot/grub/grub.cfg. The file is more messy than with its predecessor menu.lst (grub 0.99).
Thanks God there is no need to directly edit the file (though this is possible), but on newer Linuces (as of time of writting the post), there is another simplied grub config file /etc/grub/config

Hence to add the acpi=off to 1.99 open /etc/grub/config find the line reading:

GRUB_CMDLINE_LINUX_DEFAULT="quiet"

and append the "acpi=off" option, e.g. the line has to change to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi=off"

On some servers it might be better to also disable APIC along with ACPI:

Just in case you don't know what is the difference between ACPI and APIC, here is a short explanation:

ACPI = Advanced Configuration and Power Interface

APIC = Advanced Programmable Interrupt Controllers

ACPIis the system that controls your dynamic speed fans, the power button behavior, sleep states, etc.

APICis the replacement for the old PIC chip that used to come imbedded on motherboards that allowed you to setup interrupts for your soundcard, ide controllers, etc.

Hence on some machines experiencing still problems with even ACPI switched off, it is helpful to disable the APIC support too, by using:

acpi=off noapic noacpi

Anyways, while doing the changes, be very very cautious or you might end up with un-boot-able server. Don't blame me if this happens :); be sure you have a backup option if server doesn't boot.

To assure faultless kernel boot, GRUB has ability to be configured to automatically load up a second kernel if 1st one fails to boot, if you need that read the grub documentation on that.

To load up the kernel with the new setting, give it a restart:

[root@centos ~]# shutdown -r now
....

3. Disable ACPI support on kernel boot time on Slackware or other Linuxes still booting kernel with LILO

Still, some Linux distros like Slackware, decided to keep the old way and use LILO(LInux LOader) as a default boot loader.

Disabling ACPI support in LILO is done through /etc/lilo.conf

By default in /etc/lilo.conf, there is a line:

append= acpi=on

it should be changed to:

append= acpi=off

Next to load up the new acpi disabled setting, lilo has to be reloaded:

slackware:~# /sbin/lilo -c /etc/lilo.conf
....

Finally a reboot is required:

slackware:~# reboot
....

(If you don't have a physical access or someone near the server you better not 🙂 )

4. Disable ACPI fan control support on a running Linux server without restart

This is the most secure work-around, to disabling the ACPI control over the machine CPU fan, however it has a downside that still the ACPI code will be loaded in the kernel and could cause kernel issues possibly in the long run – lets say the machine has uptime of more than 2 years…

The acpi support on a user level is controlled by acpid or haldaemon (depending on the Linux distro), hence to disable the fan control on servers this services has to be switched off:

a) disabling ACPI on Debian and deb based Linux-es

As of time of writting on Debian Linux servers acpid (Advanced Configuration and Power Interface event daemon) is there to control how power management will be handled. To disable it stop it as a service (if running):

debian:~# /etc/init.d/acpid stop

To permanently remove acpid from boot up on system boot disable it with update-rc.d:
